Colleen, All I have on Ben is as follows. Do you have data on his descendants? Would very much like to get them if possible, if yours is the same fellow as mine. Don't be thrown by the different spelling of the surname.
Benjamin Rider Merkel b. Sept. 6, 1808 (recorded in the churchbook of the Rochester Dutch Reformed Church), d. unk.
If this is the same fellow, I have a few more generations of ancestors for him.
